I think the theory is correct.
arecord -v
aplay -v
report the transformation table ttable
for recording mono this seems to be default
0 <- 0*0.0833333 + 1*0.0833333 + 2*0.0833333 + 3*0.0833333 +
4*0.0833333 + 5*0.0833333 + 6*0.0833333 + 7*0.0833333 + 8*0.0833333 +
9*0.0833333 + 10*0.0833333 + 11*0.0833333
So this would explain why some people report quiet recordings!
For stereo it records lines 0 and 1.
Transformation table:
0 <- 0
1 <- 1
